Shared Crumple Zone
The upper figure shows a box of energy absorbing material with side and rear bumper shafts withdrawn into it. The

The lower figure shows the side and rear bumpers extending out of the box. If the the extended bumpers are hit in a collision, they are forced into the box, and internal plates act like pistons, and compress the energy absorbing material. The g forces on the passengers are greatly reduced. In an oblique angled collision, the shafts are designed to bend and absorb the collision over their bending distance.
Parking and entering/exiting the vehicle are easier with the extend/retract features. However, the bumpers can be permanently extended
The box can be designed as part of the vehicle, or versions of it can be an aftermarket product.
